Abstract: First information received by a first MLD on a first link is used to determine whether a BSS configuration of a second link is updated. In response to the BSS configuration of the second link not being updated, the first MLD directly transmits a data frame on the switched-to second link or the second link whose status is transited, and the data frame is not transmitted until a beacon frame is received and a latest parameter of the BSS configuration is obtained on the switched-to second link or the second link whose status is transited. A waiting time occurring before the data frame is transmitted is reduced.

Abstract: A method for coordinated communication and an apparatus for coordinated communication are provided. The method includes: a first access point (AP) sends an announcement message and/or a polling message to one or more second APs. The announcement message announces that the first AP may share a time resource of the first AP. The announcement message may further include identifier information that indicates the one or more second APs, and time information that indicate communication or channel contention of the one or more second APs in the time resource shared by the first AP. The polling message may be used to notify a second AP to start to use, at a preset time, a channel resource shared by the first AP with the second AP for communication or start channel contention at the preset time.

Abstract: This application provides a communication method and an apparatus, and relates to the field of communications technologies, to reduce a phenomenon that an acknowledge rule is violated in some scenarios. The method includes: After a receive device receives a first data unit from a transmit device through a first link, the receive device sends receiving status information of the first data unit to the transmit device through the first link, unless the first data unit meets any one of a first preset condition. The first preset condition includes: Correctly received information of the first data unit is fed back through another link, or an acknowledge policy corresponding to the first data unit is no acknowledge. The communication method in embodiments of this application is applied to a multi-link data transmission process.

Abstract: This application provides a communication method and device in a wireless local area network. The communication method includes: A receive end receives indication information from a transmit end, where a buffer of the receive end stores a log-likelihood ratio (LLR) corresponding to coded bits in an aggregated media access control protocol data unit (A-MPDU) subframe including a target media access control protocol data unit (MPDU). The receive end discards the LLR corresponding to the coded bits in the A-MPDU subframe including the target MPDU according to the indication information. According to the technical solutions provided in this application, the LLR corresponding to the coded bits in the buffer of the receive end can be discarded in time, thereby improving throughput of a system and reducing memory requirements.
